Step 3:Practice (1b)

1. Let some Ss read the adjective words in the box. Make sure they all know the meaning of each word.

2. Ss discuss with their partners. Try to write the name of a different food after each word. Learn the new words together.

Answers can be varied.

Step 4:Listening (1c－1d)

Ask Ss to look at the picture and read the sentences in 1c. Ask them to think about:

1. What are the two boys in the picture talking about?

2. Where does this story take place?

Ask Ss to close their eyes and just concentrate on the conversation they are about to hear. By shutting out any other stimulus or factors that may distract them, Ss should be able to listen and remember the facts better. When the recording ends, Ss can attempt the activity.

(Tip: Get Ss check their answers with a partner.)

Answers:

1. T  2. F  3. T  4. F  5. F  6. T

Ask Ss to fill in the blanks based on what they have heard when their eyes were closed and they were concentrating. Do they remember what they heard? Or can they guess the answers based on what they know and the context around the blanks? Once all Ss have attempted this activity, play the recording again and ask them to check their answers.(1d)

(Tip: T can play the video before Ss complete the sentences if Ss are not

strong enough.)

Answers: were invented, 1853, thin, crispy, really salty

2. What was the name of the inventor? What was his job?

3. Why was it a mistake? What did the cook do with the potatoes then?

4. How can you make food crispy / salty?

5. What can we learn from the story? Do you want to be an inventor?

Step 5:Pair­work (1e)

Ask Ss to make a conversation about the invention of potato chips.

For this conversation, get Ss to inject some exclamations into their speech instead of just using direct questions and answers. Have pairs of Ss experiment on how they can “jazz” up their conversations. Remind them of the role-play they did in Section A, activity 2d and how inflections, tones and feelings play a part.
